# Contributor Covenant Code of Conduct
|
||||
|
||||
## Our Pledge
|
||||
|
||||
In the interest of fostering an open and welcoming environment, we as
|
||||
contributors and maintainers pledge to making participation in our project and
|
||||
our community a harassment-free experience for everyone, regardless of age, body
|
||||
size, disability, ethnicity, gender identity and expression, level of experience,
|
||||
nationality, personal appearance, race, religion, or sexual identity and
|
||||
orientation.
|
||||
|
||||
## Our Standards
|
||||
|
||||
Examples of behavior that contributes to creating a positive environment
|
||||
include:
|
||||
|
||||
* Using welcoming and inclusive language
|
||||
* Being respectful of differing viewpoints and experiences
|
||||
* Gracefully accepting constructive criticism
|
||||
* Focusing on what is best for the community
|
||||
* Showing empathy towards other community members
|
||||
|
||||
Examples of unacceptable behavior by participants include:
|
||||
|
||||
* The use of sexualized language or imagery and unwelcome sexual attention or
|
||||
advances
|
||||
* Trolling, insulting/derogatory comments, and personal or political attacks
|
||||
* Public or private harassment
|
||||
* Publishing others' private information, such as a physical or electronic
|
||||
address, without explicit permission
|
||||
* Other conduct which could reasonably be considered inappropriate in a
|
||||
professional setting
|
||||
|
||||
## Our Responsibilities
|
||||
|
||||
Project maintainers are responsible for clarifying the standards of acceptable
|
||||
behavior and are expected to take appropriate and fair corrective action in
|
||||
response to any instances of unacceptable behavior.
|
||||
|
||||
Project maintainers have the right and responsibility to remove, edit, or
|
||||
reject comments, commits, code, wiki edits, issues, and other contributions
|
||||
that are not aligned to this Code of Conduct, or to ban temporarily or
|
||||
permanently any contributor for other behaviors that they deem inappropriate,
|
||||
threatening, offensive, or harmful.
|
||||
|
||||
## Scope
|
||||
|
||||
This Code of Conduct applies both within project spaces and in public spaces
|
||||
when an individual is representing the project or its community. Examples of
|
||||
representing a project or community include using an official project e-mail
|
||||
address, posting via an official social media account, or acting as an appointed
|
||||
representative at an online or offline event. Representation of a project may be
|
||||
further defined and clarified by project maintainers.
|
||||
|
||||
## Enforcement
|
||||
|
||||
Instances of abusive, harassing, or otherwise unacceptable behavior may be
|
||||
reported by contacting the project team at opensource@fairwinds.com. All
|
||||
complaints will be reviewed and investigated and will result in a response that
|
||||
is deemed necessary and appropriate to the circumstances. The project team is
|
||||
obligated to maintain confidentiality with regard to the reporter of an incident.
|
||||
Further details of specific enforcement policies may be posted separately.
|
||||
|
||||
Project maintainers who do not follow or enforce the Code of Conduct in good
|
||||
faith may face temporary or permanent repercussions as determined by other
|
||||
members of the project's leadership.
|
||||
|
||||
## Attribution
|
||||
|
||||
This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
|
||||

This means that any checks with a severity of `warning` will still pass webhook validation,
|
||||
and the only evidence of that warning will either be in the Polaris dashboard or the
|
||||
Polaris webhook logs. This will change in a future version of Kubernetes.
|
||||
|
||||
## Mutating Webhook
|
||||
By default, the Admission Controller is just pass/fail, but
|
||||
Polaris can also operate as a mutating webhook for many of the issues it checks for.
|
||||
This means Polaris will remediate the issue it finds, rather than rejecting
|
||||
the deployment.
|
||||
|
||||
To enable the mutating webhook, add `--set webhook.mutate=true` to your
|
||||
Helm instlallation command.
|
||||
|
||||
By default, the only mutation enabled is `pullPolicyNotAlways`. If you'd like to
|
||||
enable other mutations, you can set the `webhook.mutations` flag.

## Creating a new release
|
||||
To create a new release, simply tag this repo with the new version.
|
||||
|
||||
For major and minor releases, don't forget to update the Helm chart at
|
||||
https://github.com/FairwindsOps/charts
|
||||
### Patch releases
|
||||
Patch releases only need to change this repo. The Helm chart and deploy scripts
|
||||
will automatically pull in the latest changes.
|
||||
|
||||
If the release involves changes to anything in the `deploy/` folder (e.g. new RBAC permissions),
|
||||
it needs to be a minor or major release in order to prevent breaking the Helm chart.
|
||||
|
||||
1. Create a PR for this repo
|
||||
1. Bump the version number in:
|
||||
1. main.go
|
||||
2. README.md
|
||||
2. Update CHANGELOG.md
|
||||
3. Merge your PR
|
||||
2. Tag the latest branch for this repo
|
||||
1. Pull the latest commit for the `master` branch (which you just merged in your PR)
|
||||
2. Run `git tag $VERSION && git push --tags`
|
||||
3. Make sure CircleCI runs successfully for the new tag - this will push images to quay.io and create a release in GitHub
|
||||
1. If CircleCI fails, check with Codeowners ASAP
|
||||
|
||||
### Minor/Major releases
|
||||
Minor and major releases need to change both this repository and the
|
||||
[Helm chart repo](https://github.com/FairwindsOps/charts/).
|
||||
|
||||
The steps are:
|
||||
1. Modify the [Helm chart](https://github.com/FairwindsOps/charts/stable/polaris)
|
||||
1. Clone the helm charts repo
|
||||
1. `git clone https://github.com/FairwindsOps/charts`
|
||||
2. `git checkout -b yourname/update-polaris`
|
||||
1. Bump the version number in `stable/polaris/Chart.yaml`
|
||||
2. Make any necessary changes to the chart to support the new version of Polaris (e.g. new RBAC permissions)
|
||||
3. **Don't merge yet!**
|
||||
2. Create a PR for this repo
|
||||
1. Create a new branch named `yourname/update-version`
|
||||
2. Bump the version number in:
|
||||
1. main.go
|
||||
2. README.md
|
||||
3. Regenerate the deployment files. Assuming you've cloned the charts repo to `~/git/charts`:
|
||||
1. `CHARTS_DIR=~/git/charts ./scripts/generate-deployment-files.sh`
|
||||
4. Update CHANGELOG.md
|
||||
5. Merge your PR
|
||||
3. Tag the latest branch for this repo
|
||||
1. Pull the latest for the `master` branch
|
||||
2. Run `git tag $VERSION && git push --tags`
|
||||
3. Make sure CircleCI runs successfully for the new tag - this will push images to quay.io and create a release in GitHub
|
||||
1. If CircleCI fails, check with Codeowners ASAP

## Available Options
|
||||
All custom checks should go under the `customChecks` field in your Polaris config, keyed by the
|
||||
check ID. Note that you'll also have to set its severity in the `checks` section of your Polaris config.
|
||||
|
||||
* `successMessage` - the message to show when the check succeeds
|
||||
* `failureMessage` - the message to show when the check fails
|
||||
* `category` - one of `Security`, `Efficiency`, or `Reliability`
|
||||
* `target` - specifies the type of resource to check. This can be:
|
||||
* a group and kind, e.g. `apps/Deployment` or `networking.k8s.io/Ingress`
|
||||
* `Controller`, to check _any_ resource that creates Pods (e.g. Deployments, CronJobs, StatefulSets), as well as naked Pods
|
||||
* `PodTemplate`, same as `Controller`, but the schema applies to the Pod template rather than the top-level controller
|
||||
* `PodSpec`, same as `Controller`, but the schema applies to the Pod spec rather than the top-level controller
|
||||
* `Container` same as `Controller`, but the schema applies to all Container specs rather than the top-level controller
|
||||
* `controllers` - if `target` is `Controller`, `PodSpec` or `Container`, you can use this to change which types of controllers are checked
|
||||
* `controllers.include` - _only_ check these controllers
|
||||
* `controllers.exclude` - check all controllers except these
|
||||
* `containers` - if `target` is `Container`, you can use this to decide if `initContainers`, `containers`, or both should be checked
|
||||
* `containers.exclude` - can be set to a list including `initContainer` or `container`
|
||||
* `schema` - the JSON Schema to check against, as a YAML object
|
||||
* `schemaString` - this JSON Schema to check against, as a YAML or JSON string. See [Templating](#templating) below

||||
* Note: only _one_ of `schema` and `schemaString` can be specified.

## Checking CPU and Memory
|
||||
We extend JSON Schema with `resourceMinimum` and `resourceMaximum` fields to help compare memory and CPU resource
|
||||
strings like `1000m` and `1G`. Here's an example check that memory and CPU falls within a certain range.
|
||||
```yaml
|
||||
customChecks:
|
||||
resourceLimits:
|
||||
containers:
|
||||
exclude:
|
||||
- initContainer
|
||||
successMessage: Resource limits are within the required range
|
||||
failureMessage: Resource limits should be within the required range

||||

cpu:
|
||||
type: string
|
||||
resourceMinimum: 100m
|
||||
resourceMaximum: "2"
|
||||
```
|
||||
|
||||
## Resource Presence
|
||||
You can test for the presence of a resource in each Namespace. For example, to
|
||||
ensure an AlertmanagerConfig is in every Namespace:
|
||||
```yaml
|
||||
successMessage: Namespace has monitoring configuration
|
||||
failureMessage: Namespace should have monitoring configuration
|
||||
category: Security
|
||||
target: Namespace
|
||||
schema: {}
|
||||
additionalSchemas:
|
||||
monitoring.coreos.com/AlertmanagerConfig: {}
|
||||
```
|
||||
|
||||
## Templating
|
||||
You can also utilize go templating in your JSON schema in order to match one field against another.
|
||||
E.g. here is the built-in check to ensure that the `name` annotation matches the object's name:
|
||||
```yaml
|
||||
successMessage: Label app.kubernetes.io/name matches metadata.name
|
||||
failureMessage: Label app.kubernetes.io/name must match metadata.name
|
||||
target: Controller
|
||||
schema:
|
||||
'$schema': http://json-schema.org/draft-07/schema
|
||||
type: object
|
||||
properties:
|
||||
metadata:
|
||||
type: object
|
||||
required: ["labels"]
|
||||
properties:
|
||||
labels:
|
||||
type: object
|
||||
required: ["app.kubernetes.io/name"]
|
||||
properties:
|
||||
app.kubernetes.io/name:
|
||||
const: "{{ .metadata.name }}"
|
||||
```
|
||||
|
||||
* The object available via the go template is the full object, and not limited by `target`.
|
||||
* A check of `target: PodSpec` can directly access the pod specification via the go template variable `.Polaris.PodSpec`.
|
||||
* A check of `target: PodTemplate` can directly access the pod template via the go template variable `.Polaris.PodTemplate`.
|
||||
* A check of `target: Container` can directly access the container being checked via the go template variable `.Polaris.container`. The pod template and pod specification can also be accessed via the respective variables `.Polaris.PodTemplate` and `.Polaris.PodSpec`. Access to pod-level fields allows a container check to consult related fields from the pod, such as `securityContext`.
|
||||
|
||||
You can also use the full [Go template syntax](https://golang.org/pkg/text/template/), though
|
||||
you may need to specify your schema as a string in order to use concepts like `range`. E.g.
|
||||
this check ensures that at least one of the object's labels is present in `matchLabels`:
|
||||
```yaml
|
||||
schemaString: |
|
||||
type: object
|
||||
properties:
|
||||
spec:
|
||||
type: object
|
||||
required: ["selector"]
|
||||
properties:
|
||||
selector:
|
||||
type: object
|
||||
required: ["matchLabels"]
|
||||
properties:

||||

||||

|
||||
anyOf:
|
||||
{{ range $key, $value := .metadata.labels }}
|
||||
- properties:
|
||||
"{{ $key }}":
|
||||
type: string
|
||||
const: {{ $value }}
|
||||
required: ["{{ $key }}"]
|
||||
{{ end }}
|
||||
```
|
||||
|
||||
## Multi-Resource Checks
|
||||
You can write checks that span multiple resources. This is helpful for ensuring e.g.
|
||||
that every Deployment has a PDB or an HPA associated with it.
|
||||
|
||||
Here's the check to ensure that every Deployment has a PDB:
|
||||
```yaml
|
||||
successMessage: A PodDisruptionBudget is attached
|
||||
failureMessage: Should have a PodDisruptionBudget

||||

|
||||
You can audit Kubernetes YAML files by running:
|
||||
```bash
|
||||
polaris audit --audit-path ./deploy/ --format=pretty
|
||||
```
|
||||
This will print out any issues Polaris finds in your manifests.

Polaris can only check raw YAML manifests. If you'd like to check a Helm template,

you can run `helm template` to generate a manifest that Polaris can check.
|
||||
|
||||
## Fixing Issues
|
||||
Polaris can automatically fix many of the issues it finds. For example, you can run
|
||||
```bash
|
||||
polaris fix --files-path ./deploy/ --checks=all
|
||||
```
|
||||
|
||||
to fix any issues inside the `deploy` directory. Polaris may leave
